Conductivity, the concept of physics, means that the product of this amount and the electric field strength in the medium is equal to the conducted current density. For isotropic media, the conductivity is a scalar; for anisotropic media, the conductivity is a tensor. In ecology, conductivity is the ability of a solution to conduct current in a digital representation. The unit is expressed in Siemens per meter (S/m). Generally speaking, the higher the conductivity, the better the conductivity.
1. Preparation: 5 grams of soil, 200 grams of water, ATAGO digital conductivity DEC-2, ATAGO digital salinity meter (conductivity method) ES-421.
2. Pour the soil into the water and mix well.
3. Then let the mud water settle for about half an hour (to allow the fine sand in the mud to settle naturally).
4. The ATAGO digital conductivity DEC-2 was immersed in pure water for 2 minutes and the value was accurately displayed. The figure below shows that the pure water is 0.10 MS/cm.
5. Wait for the muddy water to settle and test the conductivity with ATAGO digital conductivity DEC-2, which is shown as 0.20 MS/cm.
6. The mud water content was measured using an ATAGO digital salinity meter (conductivity method) ES-421, which was shown to be 0.01%.
ATAGO provides you with more than 100 substance concentration testing solutions, welcome your inquiry.
